Climate Doomsday Clock

2°C

1,5°C

Remaining CO₂ budget for 2°C global warming used up on:

May 15 2044

Remaining time:

17 years11 months25 days 3 hrs.10 min.17 sec.

Remaining amount of CO₂ emissions to limit temperature rise to 2°C:

719.938.120.596.518 kg

Remaining CO₂ budget following the IPCC Special Report SR 1.5 (IPCC 2018)
1.5° C = 350,000,000,000,000 kg (350 gigatons = 350 trillion kg)
2.0° C = 975,000,000,000,000 kg (975 gigatons = 975 trillion kg)
Please note: IPCC SR 1.5 increased the still available CO₂ budget compared to earlier estimates. The budget available in 2015 (the year of the Paris Conference) is now 1084 gigatons instead of 750 gigatons. Thus the date when this budget expires jumped from 2034 (in an earlier version of this climate doomsday clock) to 2045.

*Note: In addition to territorial emissions of around 6.8 tonnes of CO₂ per capita, consumption in Germany causes an additional 3.5 tonnes of CO₂e per capita through imported goods and services ('embodied energy'), resulting in a total consumption-based footprint of around 10.3 tonnes of CO₂e (Source: German Environment Agency).

* estimated values

Mankind had had 75 years to emit carbon dioxide at the then emission rate in the year of the Rio de Janeiro UN Climate Conference in 1992. Now, in 2026, there are only about 18 years left at the present emission rate to keep global warming under 2 degrees. The available time runs out - action is urgently needed - TIME 2 ACT!

Global climate doomsday clock - it is still time to achieve the 2°C limit.
